P07E4Unable to Engage Park
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- With shift-by-wire or park-by-wire, P, R, N and D are requested electrically (buttons, rotary selector, automatic park on shutdown) and an actuator moves the selector shaft or the park pawl; the module compares the requested with the range actually reached. P07E4 means park is not reached or not held within the allowed time. GM gives thresholds: 2 s in 2018 tables and the ICCM of its electronic range selector (2000 ms), 6–10 s in later tables, type B with the MIL after two trips; a 2018 bulletin for LaCrosse and XT5 blames a misaligned coupling of the range control module. Ford sets it with the wrench lamp instead of the MIL – on the 2020 Escape and Corsair a misrouted park release cable, on the Mach-E software – and applies the electric parking brake. Ram 1500 (2019) sets the MIL; Stellantis names a used manual park release as the most common cause.
